  • Patent number: 6964708
    Abstract: A booth for coating objects with powder, in particular for powder painting, comprises in a manner known per se a housing, in which there is situated at least one application device, with which powder can be applied to the objects. Situated in the upper region of the housing is an air plenum, which is fed with supply air via an inlet opening. The air plenum is closed off downwardly by a filter ceiling. In contrast to known filter ceilings, the one according to the invention is air-permeable in its marginal region only, while in its central region it consists of air-impermeable material. The supply air is thus introduced into the interior of the booth as a kind of “air curtain” which flows mainly along the side walls of the housing of the booth, entrains in the process stray excess powder which has not adhered to the objects to be coated, and supplies it to at least one extraction opening situated in the bottom of the booth.

  • Patent number: 6736016
    Abstract: An airflow detection system for a vehicle paint booth. The vehicle paint booth has a first zone and a second zone adjacent to the first zone. An air velocity sensor measures airflow passing between the first zone and the second zone. An air deflector having at least one air deflection surface is located near the flow velocity sensor. At least one air deflection surface directs the airflow toward the flow velocity sensor to improve the reliability of the airflow detection system.

  • Patent number: 6730169
    Abstract: An electrostatic powder coating system that comprises a booth, the lower part of which is designed in the shape of a V, and a collecting channel (13), connected to a suction device (2) underneath, the booth having two ends, each of which has a pass-through opening for the workpieces. The collecting channel (13) is covered by floor plates (17), which can be walked upon or swung up into a vertical position, and which are provided with exhaust slots (18, 19, 20) extending in the longitudinal and transverse directions, it being advantageous for the total area of the slots be a function of the discharge of exhaust air and the velocity of the exhaust air. The floor plates, which can be swung upward, improve the ability of the booth to be walked on and thus increase the ease with which the system can be serviced and operated.

  • Patent number: 6723169
    Abstract: An installation for coating objects with powder, in particular for powder painting, comprises a booth which is known per se and in which powder can be applied to the objects by an application device. Stray powder is entrained by an air stream directed through the interior of the booth from the top downwards. The mixture of air and powder is extracted via an extraction opening in the bottom of the booth and supplied to a movable filter unit which is situated beneath the extraction opening and in which the powder is separated from the air/powder mixture for reuse. A plurality of such movable filter units are movable while suspended from a supporting-rail system, it being possible for all of these filter units, which are each intended for separating off a particular type of powder in particular one powder paint color, to be selectively brought under the extraction opening of the booth.

  • Patent number: 6616764
    Abstract: A method for cleaning an interior of a coating booth is proposed in which blast air is used as at least one of the means for cleaning. For primary cleaning of the coating booth, blast air and corresponding suction operations are used, whereby blowing and suction can be carried out simultaneously, cyclically or sequentially. The invention also relates to a coating booth. The floor and/or the ceiling of the coating booth are formed by a separate floor part and/or a ceiling part which are movable relative to the peripheral wall. The floor part and/or the ceiling part include a cleaning device which can optionally be integrated with the respective floor part and/or ceiling part. The floor part and/or the ceiling part hence operate as a cleaning device for the coating booth. The cleaning device can be displaced in the interior space of the coating booth in a longitudinal direction.

  • Patent number: 6582517
    Abstract: A compartment for powder coating of workpieces (20) which is simple in structure, cost effective, and easy to clean comprises a floor (32, 40), two sidewalls (2, 4), and two end walls (10, 12) at least one (12) of which has a door opening (16) for entry and/or exit of the workpieces (20). Two oblique walls (22, 24) are arranged symmetrically inclined with respect to each other at the inside surfaces of the sidewalls (2, 4) in the lower corner regions of the compartment, so that, together with the corner regions, they define a suction channel (34, 36) each, and with their lower edges they form suction gaps (s). The walkable floor (32) may be embodied by a stationary plate or a discharge belt. The oblique walls (22, 24) can be tilted up against or removed from the inside surfaces of the sidewalls (2, 4) for cleaning purposes.

    Abstract: A powder paint reclamation collector includes an upper chamber for collecting powder paint particles from a paint booth and a lower chamber that receives the particles from the upper chamber. A vacuum line communicates with the lower chamber retrieving the particles from the collector and transferring the particles to a reclamation system. An air chamber receives pressurized air from an air supply and communicates with the lower chamber through a porous plate. Air bleeds through the porous plate into lower and upper chambers for fluidizing the paint particles. The porous plate and an air chamber floor angle downward from the lower chamber towards the vacuum line to improve the flow of fluidized paint particles into the vacuum line.

    Abstract: A device for application of coating powder in a process including a conveyor with an air permeable conveyor surface for conveying a base sheet in a direction of travel, wherein the base sheet is coated with at least one layer upstream of the conveyor, and a powder-applying device, arranged to apply coating powder onto the base sheet. A device for directing a jet of air towards the base sheet is also arranged downstream of the powder applying device such that the jet of air effectively removes any excess coating powder from the base sheet. A suction device is also arranged to create an under-pressure beneath the conveyor surface, causing the base sheet to be pulled towards the conveyor surface, and forcing the excess coating powder to pass through the conveyor surface.
